SU LKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 361.210, dated vApril l2, 1887.

A Application filed January 24, 1887. Serial No. 225,335. (No model.)

To @ZZ whom, t may concern: Y

Be it known that I, OHARLEs CURTIS, a citizen of the United States, and a resident of Minden, in the county of Kearney 'and State of Nebraska, have invented certain new and useful Improvements inl Sulky-Ilows; and I do hereby declare that the followingisa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form 'a part of this specification, and in which- Figure 1 is a side view of my improved sulky-plow. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal vertical sectional view of the forward portion of the frame and plow-beam; and Fig. 4 is a transverse seetional view on line x w, Fig. 2.

Similar numerals of reference indicate corresponding parts in all-the figures. My invention has relation to sulky-plows 1n which the sulky-frameis attached to the plow-beam and the draft is attached to the plow-beam, so that the frame is drawn by the plow; and it consists in the improved construction and combination of parts -of such a plow, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates the axle or frame-piece of the wheeled sulky-frame, and the numeral 2 indicates a rectangular frame secured to the said sulky-frame, projecting forward. Blocks 3 are provided upon their outer sides with iianges 4, which bear against the upper and lower edges of the side pieces of the rectangular frame, serving to guide the said blocks upon the side pieces of the rectangular frame, and the said blocks are secured upon the side pieces of the frame by means of bolts 5, passing through perforations in the side pieces and in the blocks. The inner faces of the blocks are formed with guide-ribs 6, having vertical parallel edges, and the longitudinally-slotted upper ends of two bars, 7, slide between these guideribs, being adjusted by means of nuts and washers 8. The lower ends of the slotted bars are formed with slotted horizontal cross-` heads 9, in which the upwardly and outwardly bent ends of a yoke, 10, Slide. This yoke is formed with a longitudinal slot, 11, atits middle, and slides in 'a recess formed by two guideiianges, 12, upon the upper side of a block, 13, secured upon the`upper edge of the plowbeam 14 by means of a bolt, 15, having its lower bifureated end, 16, straddling the plowthe ends of the yoke and to the sulky-frame,

so that the frame will be propelled when the plow is propelled.

It will now be seen that the forward end of the plow-beam may be raised or lowered by sliding the vertical bars upward or down, causing the plow to make ashallower or deeper furrow, as desired; and by adjusting the bifurcated bolt in the slot of the yoke the beam may be set more or less toward land, causing the plow to make a wider or narrower furrow, so that the width and depth of the furrow may be adjusted by the slotted yoke and bars..

The slotted horizontal cross-heads at the lower ends of the vertically-sliding slotted bars will allow the ends of the yoke to play within them, allowing the plow to give for any unevenness in the ground and admitting of the plow being guided by the operator.

`By having the sulky-frame drawn by the plow the frame cannot ride or rest upon the plow, and thus cause it to drag or run heavy, while the plow may be supported from the frame and held from bea-ring too deep into the ground by means of the adjusting devices at the front of the frame. Vhen taking the plow from one place to another, it can be suspended from the frame by means of the ordinary hooks or attachments. If desired, the frame may be provided with any of the ordinary levers, 85e.,

for raising 'the plow out of the ground; but as f I make no claim to any such construction, I have not shownsueh devices in the drawings.

Having thus described myinvention,I claim and desire to secure by Letters Patent of the United States- IOO 1. In a sulky-plow, the combination of two bars slic'lingvertically and adj ustably upon the sulky-frame and having horizontally-slotted cross-heads at their lower ends, with a yoke secured transversely to the end of the plowbeam and having its ends playing freely in the V slots ofthe bars, as and for the purpose shown and set forth.

2. In a sulky-plow, the combination of two bars secured vertically to the sides of the sulkyframe and having horizontally-slotted crossheads at their lower ends, a transverse yoke having a longitudinal slot at its middle and having its ends playing freely in the slotted cross-heads, and the plow-beam having an upwardly-projectiug bolt secured adjustably in the slot of the yoke, as and for the purpose shown and set forth.

3. In a sulky-plow, the combination of a yoke, 2l, pivotally secured to the forward portion of the plow-beam, the wheeled sulkyframe, rods 22, pivoted to the ends ofthe yoke and to the sulky-frame, a slotted yoke secured to the sulky-frame, and means, substantially as described, for securing the forward end of the plow-beam to the slotted portion of said slotted yoke, as and for the purpose shown and set forth.

4. In a sulky-plow, the combination of a rectangular frame secured to the forward side of the sulky, two longitudinally-slotted vertical bars sliding adjustably upon bolts in the side pieces Yof the frame and having horizontally-slotted cross-heads at their lower ends, a transverse yoke having its upwardly and outwardly bent ends sliding freely in the horizontal slots of the cross-heads and having a slot at its middle, a block upon the upper edge of the plow-beam having guide-flanges guiding the yoke, a bolt having its lower bfnr- 4o cated end straddling thc beam and having its upper nutted end sliding adjustably in the slot of the yoke, a flat bar having its forward end secured upon the bolt and bent down to form a lip, a yoke pivoted upon the rear end of the flat bar, and rods pivoted to the ends of the yoke and to the sulky-frame, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature 5o in presence of two witnesses.

CHARLES CURTIS.
